The manager can give precedence to output over input and serve all in rotation on each side. Even with threads, ipc flavors of mechanisms are nice. You could do it in the old message queue mechanism, too. Since everyone is in one memory space, messages just have item pointers.
I'm sorry but I just don't know what you're trying to say.

I'm still very new to threads and locks.

GLSTENCILMASK(3G)														 GLSTENCILMASK(3G)

NAME
glStencilMask - control the writing of individual bits in the stencil planes C SPECIFICATION
void glStencilMask( GLuint mask ) PARAMETERS
mask Specifies a bit mask to enable and disable writing of individual bits in the stencil planes. Initially, the mask is all 1's. DESCRIPTION
glStencilMask controls the writing of individual bits in the stencil planes. The least significant n bits of mask, where n is the number of bits in the stencil buffer, specify a mask. Where a 1 appears in the mask, it's possible to write to the corresponding bit in the sten- cil buffer. Where a 0 appears, the corresponding bit is write-protected. Initially, all bits are enabled for writing. ERRORS
GL_INVALID_OPERATION is generated if glStencilMask is executed between the execution of glBegin and the corresponding execution of glEnd. ASSOCIATED GETS
glGet with argument GL_STENCIL_WRITEMASK glGet with argument GL_STENCIL_BITS SEE ALSO
glColorMask(3G), glDepthMask(3G), glIndexMask(3G), glStencilFunc(3G), glStencilOp(3G) GLSTENCILMASK(3G)
